To all whom 'it may concern:

Beit known that l, Jorrit THOMAS BRADY, a citizen-of the United States,residing at St. Louis. State of Missouri. have invented certain, new anduseful .Improvements in Gas Service-Cocks; and lf do hereby declare theiiollowing to he a full, clear. and exact descriptiou ot' the invention,such as will enable others skilled in the art to which it appertains tomake and use the saine, reference being had to the accompanyingdrawings. and to the letters of reference marked thereon, which form apart of this specilication.

rIhis invention relates to new and useful improvements in attachments tovalves for service pipes, affording means whereby the valve may be heldlocked either open or closed and comprises various details ofconstruction, combinations and arrangements of )arts whichfwill behereinafter 'fully described and then specifically defined in theappended claim.

l illustrate my invention in the accompanying drawings, in which iFigure l is a perspective view of a valve casing` showing myimprovements ap'pliedto the valve therein. Fig. 2 is a top plan viewshowing the val've plug open, and Fig. 3 is a sectional viewhorizontally,through thc valve casing, showing the valve closed.

Reference now being :had to the details of the drawings by letter, Adesignates a valve casing whichanay be of any. shape or size and isprovided with a plug'valve B having a stem *C* Said casing has twolaterallypro` jecting wings D and D which are parallel to each other..the former of which is provided with an aperture 2 and the latter with asimilar aperture D. Integral with said stein is a laterally projectingwing which is parallel to the wing D and is provided with an aperture Edesigned, when the valve is closed, to register with the aperture D2,tof'ming means whereby the tongue of a padlock or other device may beinserted A therethrough for the purpose of holding the vlocked in anopen, or a closed valve closed. Upon said stein is inounted at the lowerend of the casing a washer F having a laterally projecting arm with anaperture F therein which arm is positioned at right angles to the wing Ewhich is integral with said stein and mounted adjacent to the upper edgeof the casing. A nut H is mount-i ed .upon the lowerthreaded end of thevalve stein and is adapted to bear against said washer F. As the stern Cis given a quarter y a padlock or other article through said registeringapertures to lock the valve open.

Fronrthe foregoing, it will be noted that,- by the provision of themeans shown and described, a simple and efficient attachment is affordedwhereby a service valve may be relation, the washer F and the integralwing E being at all times' at. right angles to ,each other, the oneindicating that the valve is open whfe the other indicates thatthe valveis closed.

lVhat I claim to be. new and desire to secure Letters Patent is:

In combination with the casing of a service valve having laterallyprojecting paral.

lel arms provided with registering apertures, a plu'gvalve having astem,laterally projecting apertured arms uponsaid stem, one upon eitherside of the casing and positioned at -right angles to each other andadapted .to he thrown alternately so that the aper-` tures therein willregister with one or the .other ot the apertures in the projections ofthe arms upon said casing when the valve is thrown to its limit in onedirection or the other.

In testimony whereof signature in the presence of two witnesses.
